54 THE DISEASES OF DOMESTIC ANIMALS. 



any other organ. Probably if calves and heifers were systematically 

 dissected with the same care as human bodies, these cysticerci would 

 appear as frequently as the trichinae or the cysticercus cellulosse in 

 man, both which parasites were discovered in the anatomical thea- 

 tre, and without anatomical dissection would no doubt have eluded 

 the vigilance of science much longer." 



As said previously, teenia saginata is found in man in all parts 

 of the world. It seems far to exceed tsenia solium in its prevalence 

 among the inhabitants of Austria proper and Lower Germany, while 

 in North Germany taenia solium is more frequently met with. It 

 has been met with in England, and a case of invasion is also report- 

 ed in an Indian in our own country ; but well-ordered statistics in 

 this regard are so out of the general course of events in these two 

 countries, that we are not justified in assuming that the populations 

 of the same are so much favored above their fellow-men in other 

 countries. 



With reference to protection from this parasite — 



1. We must have a well-organized system of inspection of all 

 animals slaughtered, by competently educated men. 



2. The people must be educated in a knowledge of these dan- 

 gers, and also in the means necessary to their prevention. 



a. Without the active co-operation of the people, we can hope for 

 little successful reform in this country. 



3. The consumption of undercooked meat must be looked upon 

 as dangerous to health. 



Cattle are also subject to several diseases which threaten the 

 public health, from the fact that they are transmissible to man by 

 means of infectious elements peculiar to each of them. 



" Foot-and-mouth disease " is the common name given to a pe- 

 culiar vesicular eruption which afflicts cattle on the parts indicated 

 by the above name, as well as upon the udder of milch-cows. 



This disease has also been observed in sheep, swine, goats, the 

 deer family, occasionally in the horse, and cases have been reported 

 among dogs and turkeys. Further, numerous cases of infection 

 have been reported among human beings. 



Fleming says : " It has caused almost as much loss and trouble 

 to the farmers of Britain as has the contagious bovine lung-plague. 

 In 1876-'77 this disease was reported as infecting 11,064 cattle, 

 4,809 sheep, and 1,904 swine in the kingdom of Prussia. It is 

 needless to say that no statistics exist as to its extension among cat- 

 tle and other animals in the United States." 



The asssertion that animals affected with it have been exported
